SPECIFICATION forming part of Letters :Patent No. 553,554, dated January28, 1896.

Application filed May 22, 1895. Serial No. 550,230. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, WILLIAM H. DE CAMP, a citizen of the United States,residing at Fort Vayne, in the county of Allen, in the State of Indiana,have invented certain new and useful Improvements in a Combined Churnand Ice-Cream Freezer; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying draw'- ings, which formpart of this specification.

My invention relates to'improvements in a combined churn and ice-creamfreezer.

The objects of my invention are to produce a convenient and economicalmachine which can be used both as a common dairy or household churn anda cream-freezer. I atta-in these objects by the mechanism illustrated inthe accompanying drawings, in which- Figure 1 is a vertical sectionalview of the entire machine; and Fig. 2 is a detail partlysectional viewof pinion 9, with a section of the wire agitator 10.

Similar iigures refer to similar parts th rou ghout the several views.

1 is a platform or table securelyfastened to and supported by any propernumber of legs 1S so as to give the necessary stability' and strength tosustain the other parts of the machine. If desired, the legs can besecured to the floor by screws or bolts through the flanges 35.

31 is a shelf securely fastened to the legs 1S at a sufficient distancebeneath the table Q 1 to receive and support the machine thereon, ashereinafter described.

24 is a bed-plate casting resting upon the shelf 31 and rigidly securedto it by any suitable means.

23 is a conical bearing in the casting 24 and in which rests the conicalend of a vertical cylindrical rotatable shaft 5, which extends nearly tothe top of the .machine7 as hereinafter described.

Rigidly secured to the lower end of the shaft 5, just above its bearing,is a bevel gearwheel 22, and at a proper distance above the gear-wheelis a collar 20, also rigidly secured to the shaft 5. Resting upon theupper side of the collar 20 and sleeved upon 5 is a vertical, hollow,cylindrical, and rotatable metallic shaft 2. At the lower end of theshaft 2 is rigidly secured another bevel gear-wheel 19.

25 and 25 are vertical standards integral with the cast-ing 24, andhaving at the upper ends boxes in which are journaled the horizontalcylindrical shaft 26. At the outer end of 26 is secured a removablecrank'27 and at the inner end is rigidly secured the bevel gear-wheel21, which meshes on its lower side with the wheel 22 and on its upperside with the wheel 19.

The shaft 2 passes through a perforation in the table 1 and through asuitable box-bearing 17 secured upon the upper surface of said table..At a suitable distance above the table 1 to admit of free movement thereis rigidly secured to the shaft 2 a horizontal, circular, andcentrally-perforated metallic plate 36, which will rotate with the shaft2, as hereinafter stated. From its lower end to the upper surface of theplate 36 the shaft 2 is of uniform diameter; but the part 6 above theplate is conical and extends nearly to the top of the churn-body 3.

Resting upon the plate 36 and supported by it is a metallic cylindricalflat-bottomed churn-body 3 having in its diametrical center a conicalthimble 16 corresponding to the perforated plate 36 and which surroundsthe shaft 2 and is open at both ends. rllhis thimble 16 extends nearlyto the top of the churn 3 and is integral with its bottom so as tosecurely retain the contents within the churn when charged.

Above the upper end of the thimble 16 a horizontal spur-geared wheel Sis removably secured to the upper end of the shaft 2 so as to revolvewith the shaft.

Above the wheel 8 upon the shaft 5, and removably secured to it, is ahorizontal lever '7, with arms of unequal length extending from itsattachments with the shaft 5. At the end of the longer arm of 7 isattached, obliquely to the radius of 5, a scraper 11, with its outeredge just in contact with the interior sides of the churn 3. To theshorter arm of 74 is removably attached the spur-pinion 9 by a bolt andwasher 413, as shown in Fig. 1.

In the pinion 9 are perforations for the wires, which collectively formthe agitator 10 IOO and which are attached and arranged as shown in thedetail View, Fig. 2. The pinion 9 is geared with the spur-wheel S, andrevolves freely upon its journal 43.

The churn-body 3 has a removable lid et, which can be secured bysuitable clamps 15.

13 is a removable ice-tub having suitable handles 14 and in its centeraconcentric opening for the plate 36 and the churn 12 is an interiorconcentric jacket forming the circumference of the said opening, and ismade of non-corrosive metal and integral with the bottom 37 of theice-tub. This jacket is about one-third in height of the outer wall ofthe tub, and both the plate 36 and the churn 3 fit closely within theopening, but sufficiently loose to permit Vboth plate and churn torotate freely with the shaft 2. By this construction an annular spacefor the freezingr mixture surrounding the churn and permitting contactwith it is formed.

A motor attachment for operating the ma.- chine is shown in Fig. 1,which may be attached and thereby much man ual labor bedispensed with,which I describe as follows: Ver` tical upright metallic standards 42are rigidly secured to the casting 2l at one side of the standards 25.Upon the standards- 42 is mounted a horizontal shaft 41, at the outer:

end of which is attached a suitableioperating crank 33, and at the otherextremity are mounted upon said shaft a spur-geared wheel 38 and acoiled steel spring 29, having its upper end rigidly secured to across-bar rigidly attached to the standards 42. A rotatable shaft 40 isalso mounted upon the standards 12, upon which is a pinion-wheel 39,Vwhich meshes into 38, and also a pinion 30, which meshes into thespur-wheel 28, mounted upon the shaft 26. By means of the crank 33 thespring 29 can be wound up like a clock-spring, and its expansive forcewill producea rotary motion to the churn through the drivingwheel 21.

Other suitable methods of applying motive power will be suggested tomechanics.

The method of operating my invention is as follows: To use as a churnthe milk or cream is placed in the churn 3 Without filling it quite tothe upper end of the sleeve 16. The lid 4 is secured in place, and byturning the crank 27 motion is 1 communicated to the shafts 2 and 5. Itis obvious that the shafts will revolve in opposite directions -andthatthe agitator 10 will revolve about the shaft 2 and at the same timerotate upon its own axis, while the scraper 1l will revolve upon theshaft 5. The churn 3, mounted upon the plate 36, will also revolve, andby these op posite motions the contents of the churn will D the contentstoward the agitator 10.

The method of removing the contents will be so readily understood as notto need a detailed description.

For use as a freezer the material is placed in the churn and the spacebetween 3 and 13 filled with the freezing mixture, as in other freezers.The rotatory motion of the churn brings its sides in immediate contactwith the freezing mixture at all points, while the cream or other'contents to Abe frozen are thoroughly stirred by the agitator lOand thescraper 11.

Having thus described my invention, what I claim, and desire to secureby Letters Pat ent, is-
